3 Description
The AFE7900 is a high performance, wide
bandwidth multi-channel transceiver, integrating four
RF sampling transmitter chains, four RF sampling
receiver chains and two RF sampling feedback chains
(six RF sampling ADCs total). With operation up to
7.4 GHz, this device enables direct RF sampling in
the L, S and C-band frequency ranges without the
need for additional frequency conversions stages.
This improvement in density and flexibility enables
high-channel-count, multi-mission systems.
The TX signal paths support interpolation and digital
up conversion options that deliver up to 1200 MHz
of signal bandwidth for four TX or 2400 MHz for two
TX. The output of the DUCs drives a 12-GSPS DAC
(digital to analog converter) with a mixed mode output
option to enhance 2nd Nyquist operation. The DAC
output includes a variable gain amplifier (TX DSA)
with 40-dB range and 1-dB analog and 0.125-dB
digital steps.
